What is CCTV?

CCTV (Closed Circuit Television) entails the monitoring and/or recording of people, processes or property through the use of camera and other related electronic security systems.
It could be to deter theft, spy on people, for security or for many other reasons. JoZitech are proffesionals in CCTV and surveillance. This form of video security can be sub-divided into analogue and IP (Internet Protocol) solutions.

The Benefits of CCTV

  • Reduce losses due to theft.
  • Increase employee productivity.
  • Increase customer and employee safety.
  • Provide 24/7 access to your system from anywhere in the world.
  • Reduce the need for physical security.

CCTV Cameras

CCTV cameras are available in either monochrome (black and white) or colour.
The different types of cameras are Board CCTV cameras, Bullet CCTV cameras, Fixed Dome or Vandal Proof cameras, Fixed CCTV cameras (also called Static cameras), Zoom cameras, PTZ (Pan, Tilt, Zoom) cameras, High Speed Dome cameras and IP Network Cameras.
Manufacturers of quality CCTV cameras are Samsung, Techwin, Sony, Vista.

CCTV Systems

A basic CCTV system comprises of a CCTV camera, a video transmission system which sends video signals from the camera to a recording system such as a digital video recorder (DVR) which in turn sends the image to a monitor for display, viewing of playback purposes.

What is IP CCTV?

IP CCTV or Internet Protocol Closed Circuit Television, is a security surveillance system of IP Cameras and video servers which connects seamlessly with the Internet and Internet related digital services, including Wi-Fi, Wi-Max, 3G or GPRS Access connection.

IP CCTV Cameras

IP CCTV cameras are similar to standard CCTV cameras in features and functions, but offer far superior picture quality as they do not transmit their images and sound as analogue signals, but as data. They also offer remote configuration of their settings, and on some models even the image sensor of the camera can be configured as required. IP CCTV cameras incorporate built in web servers which allows for live monitoring, recording and configuration across a computer network or the internet (by connecting the camera directly to an internet connection using the relevant equipment, for example a Router to connect to an ADSL Internet connection).

The benefits of IP CCTV

  • Existing network infrastructure can be used, no extra long distance cables required.
  • IP security cameras can be moved with minimum time & effort, and cabling does not need to be replaced.
  • IP security cameras can be installed at any location, no matter the distance.
  • The same camera could be viewed or recorded simultaneously at multiple locations, controlled by multiple security levels.
  • Recording could take place anywhere, and even an existing PC or Server could be used for a few cameras.
  • Any amount of recordings per camera can take place at the same time, at multiple locations for redundancy or off-site storage.
  • Bandwidth could be controlled differently for each camera.
  • Hard drive space can be shared across many systems for recording of video or data.
  • Audio or alarms can be connected to the same encoders which transmit the video.
  • Existing alarm system could be monitored from remote locations.
  • Remote monitoring.

How does IP CCTV work?

An IP security camera “views” broadcasts the video images as a digitized signal over a LAN line (Local Area Network) where it’s then transmitted to a computer or server.
Each camera is connected to the network via a transmitter/receiver unit that converts the analogue signal into DVD quality MPEG-4 or H.264 digital video for transmission over the network infrastructure.
Depending upon the software used to manage the digital images, it can record, display or retransmit the images to anywhere in the world.
The software package can allow for analyzing data and selecting specific “flagged” items to watch out for.
True IP-based digital surveillance uses CCD cameras that use signal processing that send packeted video streams over the LAN through a Cat 5/Cat 6 cable rather than a coax cable network, utilizing greater bandwidth and standard TCP/IP communication.
If security is an issue, full digital surveillance also offers the added advantage of data encryption opportunities to protect against image tampering.
